RAG development · London
RAG development services in London
Senior engineers on your morning and lunchtime hours, UK GDPR built in, and a fixed price before we start.
Clarigo Infotech builds retrieval-augmented generation (RAG) systems: AI search and assistants that find the right information in your documents, databases and knowledge base, then answer with sources. RAG keeps answers accurate and current without retraining a model, and respects who is allowed to see what.
UK businesses most often hire us for AI automation for service businesses, logistics software and fast MVPs for startups.

What we build with RAG
Chat with your documents
Ask questions across PDFs, policies, manuals and contracts and get answers with citations.
Enterprise knowledge assistants
One place for staff to find answers across Google Drive, SharePoint, Confluence and more.
Customer support answers
Grounded answers for support teams and chatbots, drawn from your help centre and product data.
Search over structured data
Combine document search with SQL and APIs so answers include live numbers.
Permission-aware retrieval
Users only get answers from content they are allowed to see.
Evaluation and tuning
Test sets that measure retrieval and answer quality, and tuning until they pass.
How we approach RAG development
Why RAG instead of fine-tuning
Fine-tuning changes how a model writes; RAG changes what it knows at the moment it answers. For most business questions RAG is cheaper, easier to update and easier to audit, because every answer points to its source.
Getting retrieval right
Quality depends on how documents are cleaned, split, embedded and searched. We use hybrid search (keyword plus vector), re-ranking and metadata filters, and test retrieval separately from the final answer.
Keeping it current and secure
Connectors keep the index in sync as documents change, and access rules from your source systems are applied at query time so nobody sees what they shouldn't.
Measured, not guessed
We build a test set of real questions with expected answers and track accuracy, citation quality and 'I don't know' rates, so you can see improvement and catch regressions.
How we work with London clients
Time-zone overlap
London and our team in India share four to five working hours every day, so stand-ups, calls and quick decisions all happen during your morning and early afternoon.
UK GDPR
We design products to UK GDPR principles: data minimisation, clear consent, access controls, encryption and data stored in the UK or EU when you need it. We sign NDAs and data processing agreements before work starts.
Billing
Invoices in British pounds (GBP) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Industries we work with in London
London startups and service businesses work with us for senior product teams that design and build software, apps and AI with UK GDPR in mind, at a cost that makes it possible to build more and launch sooner.
Financial services and fintech
London banks and challengers need secure, FCA-compliant digital products. We build AI agents, assistants and automation around these workflows.
Professional services
Law and consulting firms automate document-heavy workflows. AI here usually means faster reporting, fewer manual steps and better customer replies.
Retail and e-commerce
High online shopping adoption makes store performance decisive. We start with one costly process and automate it end to end.
Creative industries
Media and agencies adopt generative AI for content production. We build AI agents, assistants and automation around these workflows.
